C Program for Depth First Binary Tree Search without using Recursion

C Program for Depth First Binary Tree Search without using Recursion : The following C program performs a Depth First Search traversal. Depth-first search (DFS) is an algorithm for traversing or searching a tree, tree structure or graph. The concept of backtracking is used in DFS. In this program we are performing DFS on a binary tree. In DFS, the deepest and unvisited node is visited and backtracks to it’s root if no siblings of that node exists.

Here is the source code of the C program to apply DFS on a binary tree:
